Filed: 1992-03-27
Abstract: A tension pulley (1) in a mechanical tensioning device for a traction mecanism is mounted via a roller bearing (5) on the surface of a cylindrical outer casing of a supporting element (11). The said supporting element (11) is provided with an inner boring (16) which is eccentric in relation to its outer casing surface and accommodates a carrying bolt (17). The carrying bolt (17) has an eccentric fastening boring (21) in which a fastening screw with a stationary base plate (23), preferably a crankcase or cylinder head, can engage. The mechanical tensioning device further comprises a helical spring (19) which subjects the supporting element (11) to a tension force operating in the circumferential direction around the carrying bolt (17). To create a chamber (18) to accommodate the helical spring (19), the supporting element (11) is in the form of a cup-shaped component with an inner ring-shaped hub section (15) forming the inner boring (16), a rim (14) on the front side and an outer ring section (13). The chamber (18) has the purpose of ensuring that as long a helical spring (19) as possible, and thus one with optimal spring characteristics, can be accommodated; the rim (14) is therefore arranged axially displaced from the transverse mid-plane of the roller bearing (5) and opposite the base plate (23).

Inventor: OBERMEIER PETER
IPC: H01K11/00
Filed: 1992-12-10
Abstract: A heatable body 11 is heated by means of a heating foil in the form of a metallic electrically conducting heating coil 14 embedded in a plastic sheet, adhered in a thermally conductive manner to a rear surface 13 of the heatable body of the black body radiator. At a slight distance from and slightly inclined to the heating foil surface an infrared-radiation-reflecting mirror 15 is arranged, the intermediate space between the heatable body and the mirror being evacuated. The mirror reflects the radiation coming from the heating coil and incident thereon into the intermediate spaces of the heating coil so that the radiation passes through the heating foil and is absorbed by the rear side of the black radiator. Furthermore, the rear side of the mirror and a holder are provided with a thermal insulation, for example in the form of ceramic paper 19. <IMAGE>

Title: Glass sheet division - has longitudinal and material scored lines with units to twist off edge strips with lower counter surfaces and upper retainers
Inventor: LISEC PETER
IPC: C03B33/033
Filed: 1993-02-25
Abstract: To divide glass into a number of sections of required sizes, the glass is scratched along the break lines together with at least two zero cut scratch lines at right angles to each other near at least two glass edges, forming a corner. The scored glass is fed to a table, where at least one zero cut line is broken to separate an edge strip across the direction of travel. The glass strips are further advanced with the scored lines generally parallel to the line of movement, and the zero cut line parallel to the movement line is severed to remove an edge strip. The glass material is then advanced further to a fresh section of the table. Also claimed is an assembly with one unit (50) to break off the glass edge strip across the line of travel, and a further unit to break off the edge strip parallel to the movement. Each unit has a counter surface under the glass, along the break lines and two retainers bearing down on the glass from above. A tool is lowered against the retainer on the section to be separated to twist off the glass edge. USE/ADVANTAGE - The technique is for dividing a large glass sheet into panes, with the edge strip separation integrated into the operation, for clean edges at the separated panes.

Title: Folding box for electric light bulbs
Inventor: LUEHRIG HERMANN DIPL ING
IPC: B65D59/04
Filed: 1993-03-30
Abstract: Electric light bulbs are usually packaged in folding boxes with insertion tabs for closing the upper and lower opening of the folding box. To test the light bulb, it must be unpacked and packed up again after testing. A large amount of material is used for the folding box; additionally, it has no tamper-indicating closure. The new folding box is intended to allow testing of the light bulb contained in it without unpacking; less material is to be used for producing the folding box, it is to be constructed with a tamper-indicating closure and have good properties for machining. The new folding box consists of a polygonal wrapping having a holding device which engages on the base of the light bulb and fixes the light bulb in the centre of the wrapping; the base of the light bulb remains accessible for testing. Little material is used for producing the folding box since no closure flaps are required; a construction with tamper-indicating closure is possible. Use preferably for light bulbs for lighting purposes in accordance with DIN EN 60064.

Title: AC voltage semiconductor changeover switch - acts as on=off switch via contacts of relay switched only when no current flows
Inventor: SIMMANK WILFRIED DIPL ING
IPC: H01H9/54
Filed: 1993-04-01
Abstract: The relay contacts undertake the actual switch-over function. A semiconductor switch acts as an on/off switch and helps the relay to be switched over only when no current flows. To switch on, the relay is actuated. After the relay has completed its switching process, the semiconductor switch is switched on at the null voltage point. To switch over, the semiconductor switch is switched off. The relay is actuated and the semiconductor switch is then switched on again. ADVANTAGE - Life of relay and its reliability greatly increased, interference is greatly reduced and efficiency increased.

Title: Control system for a hot-water storage tank with external hot-water production
Inventor: KAISER HARALD
IPC: F24D3/08
Filed: 1993-06-30
Abstract: Object and aim: In contrast to traditional hot-water storage tanks with internal heat exchanger, the boiler output is able to change over to hot water independently of the volume of the storage tank, with the same switching characteristics. It is possible to differentiate between heating-up and reheating. Solution to problem: By using an external heat exchanger, it is possible to adapt the heating of the hot water, as desired, to the output of the heat generator. As a result, the volume of the storage tank is independent of the output of the heat generator. By using two temperature sensors, the same switching characteristic known from traditional storage tanks with internal heat exchanger is achieved. The first sensor (1) switches on the external hot-water production when the desired temperature is undershot. The water to be heated is drawn off at the bottom of the storage tank (4), heated to desired temperature and forced into the top of the storage tank until it passes through the supply line to the external heat exchanger (3). There, the second sensor (2) is located, which switches off the hot-water production when the desired temperature has been reached. The storage tank, which is externally charged, can be adapted to any boiler output. In traditional heating installations, hot-water production is given priority, i.e. the heating-system circuit is switched off when hot water is being produced. If the storage tank cools down without temperature layering, the sensor switches on according to the differential gap and reheating takes place. Storage tanks with internal charging can then... the ... Original abstract incomplete. <IMAGE>
